Difference Qlumedit and LDTeditor

Posted by Marcel van der Steen in Explanation No Comments »

QlumeditVsLDTeditorWith every lamp measurement comes an eulumdat file. This is a photometric file enabling you to simulate light distribution and light patterns in a certain area like an office, or on streets etc.

It appears that two programs, Qlumedit, and LDTeditor, do read in differently an equal eulumdat file when symmetry is present along the C90 C270 axis.

Personally, I do not understand the way LDT editor does it.

Solarzellenpaneele oder Sonnenkollektoren?

Posted by Marcel van der Steen in Energy saving, Explanation, Solar energy No Comments »

20140626_131259_artikelIn diesem Artikel erkläre ich wie ich eine Wahl getroffen habe zwischen Solarzellenpaneele (oder kürzer Solarpaneele, bringen elektrische Energie) und Sonnenkollektoren (bringen Wärme-energie).  Ich habe schön eine Wärmepumpe (Nutzung der Erdwärme mittels Wasser) und vielen raten mir an Sonnenkollektoren zu verwenden, damit die warmes Wasser machen wenn es viel Sonne gibt. Das Pufferfass wird so extra aufgewärmt durch warmes Wasser von den Kollektoren damit die Wärmepumpe keine (elektrische) Energie anwenden muss für Heizung. Dazu kommt noch dass für die Heizung warmes Wasser eine Wärmepumpe ein niedrigeres Leistungszahl hat weil die Temperatur des Wassers hoch sein muss (45 – 50 Grad).

Dieser Artikel macht einen Energie- und Kostenvergleich zwischen beide Forme von Energieerzeugung.

How to pay easily with bitcoins

Posted by Marcel van der Steen in Explanation No Comments »

Since March 2014 OliNo accepts payments with bitcoin. Internationally it is very cheap to pay with bitcoins as the transfer fee (also called a miner fee) is about 8 eurocents. And the payment is immediate (firm confirmation after 1 hour) and irreversible; there is no bank in between! That is also a main reason why we support it: no bank is needed, and you can manage your own money. Also the politics have less influence and they cannot print additional bitcoins.

We as OliNo support a future where we as people can deal ourselves with our money we use and are not dependent from banks or politics. We give a 10 % discount if you pay with bitcoins. In this article we explain how payment can be done easily.
